In 1917, the whole entire area of Matachewan, Ontario, Canada was rather transforming when a prospector and his companion had uncovered a massive size Barium Deposit Zone. Within the same year the two prospectors had soon incorporated their own company which was identified as the Ontario Barium Company Limited. In nature the company it self became involved within this operation as it would commence land stripping and trenching phase to see what was hidden beneath the solid hard rock. As this had all occurred the new corporate owner would additionally started sinking a small shallow shaft that was sunk on the Creek Vein Zone. By 1920, most of this claimed area was rather becoming abandoned till it was re-staked by Mr. H.D Glendinning in 1930. He immediately had commence his own explorations when a half ton of rock became extracted for the purpose of sampling the area. As this had occurred the prospector would eventually move onto more exploration phases when a trenching and sampling program had uncovered three veins in 1940. But with not enough capital the young prospector decided to sell the claim of to the Independent Mining Corporation Limited in 1959. These corporate figures would additionally commence their own exploration procedures when 3,289 feet of core sample was taken. However, the company it self did not last for long as the mine became staked by the Extender Minerals of Canada Limited in 1975. During this time period the company was well in operation within its two vein zones. In addition this had included making an adit on the shores of Mistinikon Lake, and had also included developing another adit on the Creek vein zone that was also not located to far from the shore lines of Mistinikon Lake. More so the Creek Vein adit was rather an incline shaft method which was driven vertically like a ramp towards the ore-body. The other adit that was rather located on the shorelines of the lake had been driven straight through the hard solid rock to intersect the Barium ore-body. In nature the company was well onto something when it was now shipping the first ever Barium that came from the Glendinning Barium Mine. As the ore started to become weakened the company would soon move onto more exploration phase when land stripping was achieved to explore the veins between the already exhausted vein zones. This would also commence trenching phase towards finding the main extension of the westward vein that was already mined on Claim GG4223 in 1997. Another study was commenced by Extender Mineral of Canada Limited as it wanted to access the beneficiation of the Creek Vein Zone Prospect.

1975 – Extender Minerals of Canada, Ltd.Besides gold deposits being the only source of resources the Matachewan Area of North=Eastern, Ontario, Canada was also home to many Barite Deposits. One of these small-scale operations which had came into production was commonly known as the Glendining Barite Mine. At the time, it was rather known as a small-scale barite mine project owned by Extender Minerals of Canada, Ltd. Most of the property in 1975 was mainly active in Open Cut methods for Barite production, and other minerals such as purple Fluorite, and Hematite ores. It was also within this time period of operating when the company had hauled it’s the Barite to the On-Site milling facility.

1976 – Extender Minerals of Canada, Ltd. Mining within 1976 had continued onward when the company was focus on developing the open-cut. It was also reported that this open-cut was rather made on the main barite deposit. Prior to this it became determined that the ore reserves of the Barite were slowly depleting which resulted in more exploratory work. Diamond drilling that was done on the mined-out vein had shortly after indicated extensions to the vein at depth. Most of this diamond drilling program had also intersected a flat lying Gowganda Formation. This newly indicated zone had also represented further mining which was continued onward from June to November. Much of the ore that was taken out had also been transported to the on-site crusher, and milling facility to prepare it for commercial shipment. Mining from the Glendining Barite Project Resulted in several tonnes of ore that was awaiting milling, and became stockpiled.

1977 – Extender Minerals of Canada, Ltd.Mining operations at the Glendining Barite Deposit in Yarrow Township had continued in 1977. Ore at the time that came from this project was mainly being taken out by open-cut methods once the snow had melted. Most of the ore at the time was being stockpiled in several locations and awaiting treatment procedures. All mining operations at the historical Glendining Barite Project continued onward till about 0.3 m of snow had closed down this mine for the season. Ore that was taken from this location was also haulted to the companies milling facility in Powell Township. Other barite deposits were also being prepared for mining when a truck haulage road became constructed to the Browning Lake Barite Deposit in Ciaro Township.

1978 – Extender Minerals of Canada, Ltd. All mining operations at the historical Glendining Barite Mine had once again commence in 1978. Prior to this the company had additionally brought in two trailers which were used to accommodate the workers. For the most part mining operations had continued till the snow cover became to deep for the company to work in. Other major changes would also take place when the company had focus on developing a steeply dipping stope decline below the open-cut.to mine the extensions of the main Barite vein. Production that came from this mine was also being stockpile while some ore became milled in Powell Township.

1979 – Extender Minerals of Canada, Ltd. It was in 1979 when mining operations were discontinued as the company look for better Barite Deposits else where. A small amount of mining was taking shape within 1980, but was shortly discontinued as the company was awaiting approval to commence operations on a new Barite deposit in Timmins, Ontario, Canada.

1988 - Extender Minerals of Canada, Ltd. Extender Minerals of Canada, Ltd had continued operations at their Barite Mine in Yarrow Township, and produce some Barite from the New Ryan Lake Mine in 1988. It was also during this time period of operating when mining operations were rather resumed at the Glendining Barite Project.

1989 - Extender Minerals of Canada, Ltd. Even more production during 1989, was achieved by Extender Minerals of Canada, Ltd, within the operating year of 1989. It was during that time period when the company would produce an average of 10,000 tonnes of barite from its milling facility in Yarrow Township. Other plans at the time were also being made as the company had wanted to increase its production within the Glendining Barite Project.

1990 - Extender Minerals of Canada, Ltd. Production from the Glendining Barite mine had rather amounted 10,000 tonnes of Barite that was milled in Yarrow Township. Ore Reserves within the mining operation at also stood at 100,000 tonnes of Barite ore that still remained in 1990.

1991 - Extender Minerals of Canada, Ltd.Within the operating year of 1991, Extender Minerals of Canada, Ltd had rather produce 10,000 tonnes of Barite that was mined, and milled in Yarrow Township. Other plans at the time were being made towards building a break shoe factory within Matachewan, Ontario, Canada.

1992 - Extender Minerals of Canada, Ltd. Mining operation at the Glendining Barite Project had continued to operate throughout 1992, and a total of 10,000 tonnes of Barite was produce from it underground mining project. Milling at the time was also rather being done within Yarrow Township, which is west of Matachewan, Ontario, Canada. Barite that was produce from the milling facility in Yarrow Township, had rather been sold to the Canadian Markets. Within 1992, the company was mainly selling the fine Barite to manufactures who produce various products, including brake linings, paints, plastics, and mold lubricants at several base metal smelters in Canada.

The Glendinning Barium Mining property is located on Asbestos Mine Road pastMatachewan, Ontario. This road is very maintain due to the mining atYoung-Davidson Mine. When you cross the Mistinikon Lake Bridge you willcome across several roads leading into the mine area. Most of these roads areall fill in by the ministry of natural resources. Only one road access mine #2 whichalso prohibits access to it. One indication of this mine is found through the ministrysigns which prohibit people from entering this site. In many cases its due to theatmosphere of the mine site which contains hazards. When exploring mine sitesyou always have to be aware of risky challenges. Some of these obstacles occurthrough mine ventilation shafts, expose shafts, or even lose concrete structures.Generally the mine it self was a 2 mine production level located on the right and leftside of Mistinikon Lake. In nature this mine was commonly know to produce Barite.Back in the late 1950s several companies took pride in running this mine till it shutdown in 2001. In these photo is where the Glendinning Barium Mine was first found. The rampis official cave in but ramp #2 is still alive. When you enter the Glendinning Barium Mine propertyyou will see several massive size waste rock tailings from the last producers. In manycases these tailing piles still contain massive size Barite samples. Back in the day manymine companies would provide accommodation for their own workers. When it came tothe Glendinning Barium Mine property, this mine site provided 4 trails to accommodate it's workers.Only one of it's larger size trailers remains on this claim
